Most horrific pathetic service ever

The worst most horrific service I've ever experienced!!! For 2 days I've been trying without success to speak to someone who can cancel and reverse a debit order. They call me back after lodging a complaint but transfers me and let's me hold on without anyone answering on the other side. They refer you to the website where I've authenticated myself 100 times and still don't speak to someone who can resolve my query. I ask for a Manager there is none. I ask for someone to call me back they can't. ***??! I'm supposed to be a private client oh but there's no banker assigned to me, sorry you can't be helped. What has become of FNB??! How is your technological advances or lack thereof helping you deliver a better service? You have less ppl inside banks.. So who answers your phones. Is there anyone home????
